Impressive noise blocking, watch the video on amazon.com to get a good idea on how it works. (via amazon.com)

this rocks

This is one of the few products which actually accomplish the difficult task of blocking out unwanted background noise. This is a bluetooth cellular headset with advanced witch craft technology which only allows your voice to be heard through its microphone.

I am not exactly sure how it accomplishes this feat, but all I know is that it works. I can be driving in my car playing my music at a comfortable volume while using this headset and the person on the other end of the line can't hear a darn thing except for my soothing and sexy voice.

The best out there!

Jawbone Headsets($120) It has good sound quality and blance to design.

incredible packaging. custom fit. plug an play. and one of the best headset out there. folks couldn't believe how clear i sounded on it

This sleek looking headset called the Jawbone is the highest rated bluetooth headset on CNN and it's available in 3 colors.
Very cool.

This is the best bluetooth headset in the market: bar none. It utilizes military grade noise cancellation via the soft rubber nipple to sense when you are talking and when you're not. Everyone customer I've had try the jawbone has kept it. Even in a room full of people talking, I can maintain a nice quiet conversation with clients. Aliph has also done a nice job of including different ear loops and things to customize the jawbone to fit on your ear. This thing will absolutely NOT FALL OFF.

Battery life is also impressive. I've used it off/on for 2-3 days without needing to charge it. In addition to an AC charger, a handy USB charger is also included, so you can just plug it into your laptop and juice that baby up.
